Well, I tried putting that file on an empty flash drive, putting it into the scope, rebooting it and nothing....
I think mine has a newer version of the firmware.... 00.04.01.07.00 (00.04.01 SP7)
I would try the hex hack, but I don't have this firmware to edit....
I tired both the version you linked, and the MudMan link... and neither will prompt the scope to update...
